在Tomcat中部署GWT/GWTP应用

Question

我知道这可能与编程没有直接关系。我希望它能在这里放得下。我有一个GWTP web应用程序，在开发模式下运行得非常好，无论是从eclipse还是从命令提示符运行mvn gwt:run。现在我尝试在本地将它部署到Tomcat 7。我运行gwt:compile并将zip文件(重命名为.war后)复制到webapps文件夹中。该应用程序列在Tomcat的管理器gui中。但是当我尝试导航到localhost:8080/appname或localhost:8080/appname/Project.html时，我只得到404错误。我错过了什么?为了完整起见，下面是我的pom.xml:

谢谢:)

Answer 1

似乎您的gwt-maven-plugin 目标不绑定到任何maven 阶段。试试这样做:

<executions>
    <execution>
        <phase>compile</phase>
        <goals>
            <goal>compile</goal>
            <goal>test</goal>
        </goals>
    </execution>
</executions>

Answer 2

为了使它运行，您需要按照Vadim所说的做，但也必须将此添加到pom.xml:

    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <lifecycleMappingMetadata>
                        <pluginExecutions>
                            <pluginExecution>
                                <pluginExecutionFilter>
                                    <groupId>org.codehaus.mojo</groupId>
                                    <artifactId>gwt-maven-plugin</artifactId>
                                    <versionRange>[2.4.0,)</versionRange>
                                    <goals>
                                        <goal>resources</goal>
                                        <goal>compile</goal>
                                        <goal>i18n</goal>
                                        <goal>generateAsync</goal>
                                        <goal>test</goal>
                                    </goals>
                                </pluginExecutionFilter>
                                <action>
                                    <execute />
                                </action>
                            </pluginExecution>
                        </pluginExecutions>
                    </lifecycleMappingMetadata>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>

如果您指定编译阶段为<phase>prepare-package</phase>，则在调用mvn package时，它将作为打包前的最后一步执行。
